Arrow HELP! 6.0 Wont Start

Here is the deal, this truch has had a hesitiation for about 6 months. When you are cruising at highway speeds every so often it will kinda bog down. If you slowly press on the accelerator it gets worse. If you step on the accelerator it will down shift and clean right out. This has been going on.
Well the other day the wife was driving at highway speed and she was slowing down and the truckk just seemed to shut off. She coasted to a parking lot and attempted to restart it. No luck
So got it home, plugged in the computer and it has not registered any codes related to the engine. The fuel tank was about 1/8th.
So I added 10 gallons to it. Changed the fuel filters and I have been cranking it over attempting to get it to refire. It is cranking over well right now and kinda acts like it wants to start but just never does it. kinda out of ideas without throwing $$$ away. I spent $100 on the fuel filters with no luck. What can I do now? I have noticed that after cranking it over for 5 seconds the oil pressure gauge raises up a ways. Is that normal?
Anyone got the majical solution?
This is a 2003 F-250 with the 6.0 and about 140,000 miles on it.

Sounds like a fuel delivery problem. Remove the secondary fuel filter and cap. Have an assistant cycle the key to the RUN position. Does fuel fill the housing rapidly? Do you hear the fuel pump cycling when you cycle the key between the OFF and RUN positions? If answers are yes to all of the above, you'll need a scan tool (not a code reader) to do some live data monitoring to determine the cause of why it's failing to start.
